Hub - SmartThings cloud platform communication details

[JDRoberts]

At the present time, all customer written code runs in the cloud. All of it, whether it is a smartapp or a device type handler.

The only stuff which is allowed to run locally is distributed in firmware to every SmartThings customer, and so is limited to the official smart lighting feature and a small bit of the official smart home monitor feature.

From a customer developer’s point of view, the hub is basically a box of antennas.

From time to time, SmartThings staff said that they would like to see this change so that there could be local custom libraries, but no timeline has been given and nothing in the development direction currently seems aimed towards that.

Continuing the discussion from What's the deal with Nest?: Correct. I was answering this question below in the global sense. i.e., There will always be the possibility of various benefits available to Official Device Handlers and SmartApps that are not available to un-certified Community Developed ones. At the moment, the local processing benefit is inapplicable to Nest in either case. I’m not sure ST has guaranteed that community developed SmartApps/Device Types will be included in local processing right after certification. Yes, it may be included down the road, and this is not yet clear on how or what the process is to enable community developed stuffs to run locally.
